Mentions of Claude in UK job ads grew 74% between April and June this year. ChatGPT, over the same two months, grew 17% – Claude is now growing more than four times as fast<\/span>.<\/p>\n

It’s the standout number in the latest Adzuna AI Mentions Index<\/a>, our look at how employers are writing AI requirements into job ads. But there’s more going on underneath it – AI requirements are spreading through UK hiring faster than we’ve seen since we started tracking this, and mostly in places you may not expect.<\/p>\n

Here’s the update, two months on from our last one.<\/p>\n

A new tool is winning<\/strong><\/h3>\n

Claude overtook ChatGPT in UK job ad mentions back in April 2026. By June it had all but caught Microsoft Copilot, which has led the field since we started measuring:<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t

Copilot’s lead is partly a numbers game – when a company rolls out Microsoft 365 Copilot across the whole workforce, that shows up in job specs at scale, whether or not any individual employee asked for it. Claude’s rise looks different. It’s newer, it’s sharper, and almost all of it has happened in the last six months. Claude’s share of all named-tool mentions has gone from 24% in April to nearly 30% in June. We will be keeping a close eye on this over the summer.<\/p>\n

Tech still leads, but it’s not where the growth is<\/h3>\n

June’s headline figure: 21,169 UK job ads mentioned AI, up from 18,000 in April and 12,383 a year ago. That’s 2.62% of all UK job ads – up 78% on last June.<\/p>\n
